You are sampling a signal which consists of a mixture of 160, 164 and 168 Hz sinusoids and which you want to resolve in your FFT. If you are storing 4096 samples, what is the range of sampling frequencies you can use such that you don’t violate Nyquist theorem and still meet or exceed the needed resolution when you perform the FFT operation on the full set of collected data.
a. any frequency greater than or equal to 336 Hz
b. less than or equal to 16384 Hz but greater than 336 Hz
c. less than or equal to 4096 but greater than 336 Hz
d. less than or equal to 8192 Hz but greater than 336

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
